Hint:

  • Iterate the mentioned keys using a loop
  • Next, check if the current key is present in the dictionary, if it is present, remove it from the dictionary

To achieve the above result, we can use the dictionary comprehension or the pop() method of a dictionary.

Solution1:Using the pop() method and loop

sample_dict = {
    "name": "Kelly",
    "age": 25,
    "salary": 8000,
    "city": "New york"
}
# Keys to remove
keys = ["name", "salary"]

for k in keys:
    sample_dict.pop(k)
print(sample_dict)

Solution2:Dictionary Comprehension

sample_dict = {
    "name": "Kelly",
    "age": 25,
    "salary": 8000,
    "city": "New york"
}
# Keys to remove
keys = ["name", "salary"]

sample_dict = {k: sample_dict[k] for k in sample_dict.keys() - keys}
print(sample_dict)
